MEANS FOR ACCELERATING TRAFFIC.

FJLED AUG. 24,1922.

Patented den. l6, lean GEORGE WASHINGTON PRICE AND ALBERT 7 Il'iEAlQS FOR ACCEZEJEEEELTLYG Application filed. August 3.922.

T all whom it away concern:

Be it known that we, Gnonon Vl asnlnorozv -PRICE and ALBERT HENRY ORROK, citizens of the United Eltates, residing at Brooklyn; in

the count of Kings, State of New York, have invented a new and useful Means for Accelerating Tratlic, of which the following is a specification.

. This invention relates to means forlhan dhng trailic and more particularly to unproveinents in roadways and the like to increase the trafiice-handling capacity thereof.

A feature of the invention consists in the provision of a plurality of superposed levels in a section of the roadway and of a shift able section or table at one or both ends to connect the single-level portions of the roadway with any one of the superposed levels at will. The term roadway may refer either to ahighway or to a railroad.

According to'one form of the invention, one of two roadways crossing at grade may be provided with an additional level with a sullicient clearance between it and the main roadway for the vehicles to be accommodated and with shiftable sections or tables 7 which may serve as parts of the main roadway or may be shifted into connection with the additional level so that trailie may he directed along the additional level and carried pastthe other roadway without interferenc with the traffic on the latter.

According to another form of the invention. superposed tracks and platforn'is may be provided at railroad stations or the like -and also shii'table tables to cooperate with the track on any one of said levels to connect it with single-level tracks at one or both ends of the station. By this arrangement it 40 is made possible to handle more trains at the station. and to enable one train topass another without taking; up any more room laterally than would he done by a single track.

other features and advantages will hereins-liter appear.

- In the accompanying drawings,

Figure l is a view,.,partl v in section. showing the invention applied to one of two roadways at a crossing. the movable tables being lowered to direct trail-lo under the cross way.

Figure 2 is a view similar'to Figure '1 butshowing' the complete crossing.

Figure 3 is a view illustrating the inven' table 5, positioned as shown in GRRQWEK,

'tion asapplied to railroad havii'ig GU tracks on diilerent levels.

In Figure l. are shown cnrhs l bounding the roadways and cartraclts '22 on a roadwav 3 crossing a second roadwa i order that rush-hour tratlic may tlow l-onno tinuously along" roadway 3., roadw provided with slnl tahle tables 5 positioned at convenient distances from and on oppo' site sides of roadway 3 and so mounted that, when desired. they may he shifted from their positions flush with roedwayvs to the positions shown in Figure l to divert to the lower level or suppleuientau-3 roadw (5. This enables through traliir on both road-- Wi s to he carried on without interference. Inasmuch as the tables 5 take up only part of the width of the roadvui -lvohirles may be turned from one roadway into the other when desired.

'lheferably the tables 5 are, as indicated in Figure 1, pivoted at their out-er ends; adjacent the level of the main roadway r. This showing is, however, nierelv illustrative and the changing of ti 3 level in use may be e fected in any suitable manner. range-merit of levels may also he changed. To shift tie tables use may he made o'l zit-- able nie'hz-ii-zlisni ()Ptl'tll'ttl l v eh-wlrie. ll Y" draulim or other power. l'se may also he made (it counterweights.

In Figure the invention is illustrated as applied to a railroad or subway r-ltlll l'll having upper and lower platlmiiu-i f and ll associated with upper and lower inn-lo: or levels ll! and h respectiv ly. idhi'l'tahl tables enable trains on 12 to luzlll and unload at either oi the platlorus. thus rendering it. possible to handle a greater amount oi trallic than would otherwise be possible. E);

This form of the invention may he used as 'l'ollmvs: Assume that a train t'roui l he :11"

left (Figure 3) has been direrted by the left hand. tahle to the track or love Nl'nle the train on the lower level is he unloaded and loaded. the left hand tablmay be wung to its upper pa. 2

shown in n igure o, and the i run in on track 10. ll 1 ant is l' L unloaded and train may be run out 21' r;

".1 may 1e second This tuiei*ntion.n1av he repeutet or the tables may be shifted for other purposes such, for example, as to enable one train to pass another.

Variations may he resorted to within the scope oi the invention, and portions otlthe improvements may be used without others.

Having thus described our invention, we claim:

1. The combination w th two single-level roadway sections, of an intermediate twolevel section and tables at the ends of the intermediate section shiltable to connect the single-level sections to either the upper or the lower level of the interinodiatm,section.

2. The combination with two singledevel sections of a roadway, ot an intermediate section having two levels, one of which is level with the single-level sections and tables at the ends oi the intermediate section shiftable to connect the single-level sections to either the upper or the lower level of the intermediate section.

3. The combination w th two singledevel roadway sections. of an intermediate twolevel section. the upper of the two levels being level with the single-level section at one end of the intermediate section, and tables at the ends of the intermediate section shittable to connect the single-let el sections to either the upper or the lower level of the intermediate section.

4. The combination with two single-level roadway sections, of an intermediate twolevel section,.each of said single-level sections being level with one of the levels of the two-level sections, and tables at the ends of the intermediate section shittable to connect the single-level sections to either the upper or the lower level of the intermediate section.

5. The combination with a roadway, of a second roadway crossing the first at grade and having an additional level at the crossing, traffic-shifters, one at each end o the additional level, shittable to positions with the main portion of the second roaday or to positions to connect the ends of the additional level to the main portion of the second roadway to cause trafiic on the second roadway to cross the first roadway but at aditierent level.

(3. The combination with a roadway, of a second roadway crossingthe first at grade and having an additional level at the crowing, and tables at the ends of the additional level hinged at. their outer ends adjacent the surface of the second oadway to he swung into position to direct traffic on the second roadway across the first roadway at grade or into position to cross along the additional level.

.7. The combination with a singledevel roadway, of a two-level extension thereof, and a shil'table table between said roadway and said extension and mounted "for movement to a position to connect the single level roadway with the upper level are) another position to connect the single-level roadway with the lower level.
